1. Place your piece of cardboard inside your t-shirt, and lay it down on a flat surface.

2. Using chalk, outline the design you want to appear on your shirt. This can be as simple or as intricate as you like.

3. Pour a small amount of bleach into a plastic cup, and go over your design in bleach with your paintbrushes. Be careful not to touch the bleach with your bare hands, as this will sting. (A lot. Trust me.) Don’t worry if the design doesn’t show up right away. Allow to dry.

4. Repeat your design as many times as you’d like. For a more rustic look, carefully shake the paintbrush over your shirt to create a splatter effect.

When finished, your t-shirt should look roughly like the one pictured below. To be safe, I would recommend washing your shirt before wearing it to remove any excess traces of bleach.
